对双目立体视觉摄像机标定方法进行了分析，通过Halcon标定板快速求出双目摄像机的内参和外参。在此基础上进行扩展，分别对相邻的摄像机进行双目标定，通过刚性转换，借助Halcon平台丰富的函数算子，最后把8个摄像机统一到惟一的世界坐标系，达到多目标定的效果。实验证实了多目标定的可行性与正确性，突破了以往多数仅以双目摄像机系统进行三维测量的格局，为在特定情况下不能显示在惟一双目摄像机系统视野范围内的目标物体进行测量打下了坚实基础。
對雙目立體視覺攝像機標定方法進行瞭分析，通過Halcon標定闆快速求齣雙目攝像機的內參和外參。在此基礎上進行擴展，分彆對相鄰的攝像機進行雙目標定，通過剛性轉換，藉助Halcon平檯豐富的函數算子，最後把8箇攝像機統一到惟一的世界坐標繫，達到多目標定的效果。實驗證實瞭多目標定的可行性與正確性，突破瞭以往多數僅以雙目攝像機繫統進行三維測量的格跼，為在特定情況下不能顯示在惟一雙目攝像機繫統視野範圍內的目標物體進行測量打下瞭堅實基礎。

The calibration method of binocular stereo vision camera is analyzed,and the internal and external parameters are quickly solved by Halcon calibration plate. Based on the extension of calibration technology,the two adjacent cameras are calibrated with binocular vision respectively. The eight cameras are unified into a unique world coordinate system by rigidity con?version and the function operators obtained by Halcon platform to achieve the effect of multi?view calibration. The feasibility and correctness of the multi?view calibration were confirmed by experiments,and the pattern of three?dimensional measurement using binocular camera system was broken. The technology lays a solid foundation for the measurement of target object which can′t be showed entirely in the visual field of unique binocular camera system in the particular case.
